To determine The probability of both of these occurring, you would multiply the probability of each together. So, there is a 1/7 chance of the first salesman getting the right key, and 1/6 chance of the second salesman getting the right key. 1/7 x 1/6= 1/42 chance of both occurring.

Answer:
4.4 L
Step-by-step explanation:
Given:
Water required for every 2 miles = 1 quart
Total distance traveled = 15 km
Now,
1 km = 0.621 miles
thus,
15 km = 0.621 × 15 = 9.32 miles
Therefore,
Quarts of water required for 15 km (9.32 miles) =
= 4.66 quarts
also,
1 quart = 0.95 L
therefore,
4.66 quarts = 4.66 × 0.95 = 4.427 ≈ 4.4 L
